Enzymes Can Catalyze a Reaction Only If

Question

Enzymes can catalyze a reaction only if
A)they encounter a molecule of ATP.
B)their active site is sufficiently oxidized.
C)they have both products in their active site at the same time.
D)they encounter a substrate that fits their active site.

Accepted Answer

Enzymes are specific in their catalyzing function, and can only catalyze a reaction if they encounter a substrate that fits precisely into their active site. Without a proper fit, the enzyme cannot catalyze the reaction.
